Your Extraordinary Underground Utility Locating Contractor

Hawaii Utility Locators can help keep the project on budget and the team safe by providing full-service utility locating for both private and public lines. However, one call state locators, such as 811 services, can only help to locate the public utility lines. Although their service is valuable, it can still expose you to delays and damages, and it does not take into account the many private utility lines.

Hawaii Utility Locators will offer you a comprehensive range of utility and reporting options, such as a basis field sketch, marks on the ground, and a full-blown AutoCAD report that shows buried storm drain, electrical, sewer, water, communication, and gas lines. Our expert Project Managers use state of the art technology to provide records for future reference by providing the permanent utility location record.

Do Not Dig Before Calling A Private Utility Locator

Underground private utility locating is important for construction projects that involve subsurface excavation. The property owners and excavation team should locate and avoid any public or private underground utility lines under the construction site. Accurately mapping and avoiding these utility lines can help them avoid potential injury to their excavation team, expensive damage, and costly delays.

Using ground penetrating radar for utility locating

Utility detection is important for construction projects that involve subsurface excavation because it ensures the overall success of the construction project. Ignoring it leads to an increased risk of injuries taking place on the construction site, turns the schedule into chaos, and multiply budget overruns. Every construction project needs a state-sponsored public service, so the standard is one-call utility locating.

However, this service is only for the areas that serve the interest of the public. Connecting with expert private service providers like Hawaii Utility Locators can help you achieve the complete success you are looking for. At Hawaii Utility Locators, we offer a comprehensive range of reporting options, such as a basis field sketch, marks on the ground, and a full-blown AutoCAD report that shows buried storm drain, electrical, sewer, water, communication, and gas lines. With our reports, you will have the location of permanent utilities for future reference.

Injury Prevention And Utility Locating

Hawaii Utility Locators prioritize safety and injury prevention because it is one of the top priorities of our many clients. We take great pride in safety and injury prevention and it is the most important thing of all of your services. Damaged or compromised electrical lines and gas and sewer utilities can expose your team to danger. To prevent injuries and keep your construction site safe and save time and money, accurately map and locate the utility lines under your construction site.

Our utility detection services will help locate storm, electric, sewer, gas, water, oil, communications, and steam lines. We help locate these utilities to prevent both construction workers and utility contractors from accidental strikes, which is one of the main sources of injuries in construction sites.

Injury prevention is important for employee safety. It also keeps projects running on budget and on time. To be certified for field duty, our project managers undergo training in all aspects of project safety. And they stay current on all safety developments by taking monthly refresher courses.

Utility Locating Project’s 5 Cost Factors

1) How intricate is the utility locating target?

• Is utility congestion low or high in that area?

2) The quantity and type of utilities being located.

• This includes critical subsurface utilities, such as storm and sanitary sewers; power, water, and gas lines.

3) The size of the area that requires inspection.

• The cost depends on the size of the area that requires utility scanning.

4) The scope and detail the project requires.

• Google Earth imaging, field sketches can help control the cost. It is much affordable to request simple painting/flagging utility locations. However, it is expensive to request detailed AutoCAD reports of our findings.

5) Difficulty Accessing the Site.

• The restrictions and limitations to access the site in terms of times and days can impact the cost of the project.

Ground Penetrating Radar Utility Locating Services 6 Frequently Asked Questions

1. Is it possible to find plastic pipes using GPRS?

Yes. Applying the technology and expertise to your project site can help you discover the various pipe compositions that exist in the industry.

2. Is it possible to determine the type of utility located using GPRS?

No. Our project managers can help determine the type of utility we have found because it is not possible to determine it using our equipment. Our project managers use their knowledge and experience to determine its type by tracing the line where it surfaces.

3. How accurate is utility locating?

Our utility locating is very accurate. Precisely, depth accuracy at +/- 10 to 15% and + or -6 inches to the center of the utility we find.

4. Is it possible to get permanent records of your findings?

Yes. We provide a detailed AutoCAD report and a field subsurface utilities markings map.

5. What is the size of the area you scan for utility locations in a single day?

The size of the area that we can accurately scan in a single day varies because it depends on the project site itself. It is easy and quick to complete many acres of vacant or green fields that are scheduled for residential development because we expect the congestion of utilities is low. However, it is time-consuming to scan a small property, which is located on a busy metropolitan street, because the congestion of utilities is expected to be high.

6. Is it true that a high water table or saturated soils are detrimental to the results produced with ground penetrating radar?

It can be. The equipment using the GPRS is effective, but the moisture can inhibit it. To learn more about the soils native to your project, we highly recommend you contact the local expert Hawaii Utility Locators project manager.

Know The Difference Between Private Utility Locating Services And State Agencies!

It is hard to compare Hawaii Utility Locators and state one-call services such as 811 because the two do not compete. For evaluating and locating subsurface utility lines, we STRONGLY encourage construction manages to use both Local call systems and Hawaii Utility Locators. 811 services are mainly used to located local utility lines, up to the meter of your property, or connection point. The information is valuable, however, it does not show a complete picture of what is buried under your job site.

On the other hand, the property owner is responsible for the private utilities. In the United States alone, almost 65% of all buried utilities are customer-owned and private utilities.

At Hawaii Utility Locators, we highly encourage our clients to supplement their local 811 one call system with our more complete utility locating services. Using both services does not pose any risk. And each service provides our clients with an accurate and most complete depiction of subsurface utility hazards on the job site.

State Agencies


It is easy to use GPRS to locate ALL buried utility lines in the excavation area, such as:

• Communications (fiber, cable TV, phone data)

• Secondary electric (480 volt/220/110 conduits, signage, site lighting)

• Water service lines (metal or plastic)

• Misc. utility lines like chemical transport lines such as nitrogen, oxygen, chilled water lines, steam, etc.

• Sewer lines (including field tile pipe, leach fields, septic tanks, etc.)

• Gas lines (metal or plastic)

Private Utility Locators


State Locators, such as Call 811, are used to locate ONLY public utility lines, including:

• Main Storm and Sanitary Sewer

• Gas and service lines (only if it uses tracer wire or metallic pipe)

• Communications (fiber, Cable TV, data, phone)

• Primary Electric

• Water force mains and some service lines and water force mains, specifically only on public property, such as easements, right-of-ways, streets, etc.
